Plan your weekend Dec. 15-17: Katy Perry, boat parades, Star Wars parties, comics Gilbert Gottfried, Michael Carbonaro

In St. Petersburg, a Star Wars Bar Crawl with costumes encouraged starts at 2 p.m. Saturday ... Here you’ll find original art and holiday decor with an edge, like Frank Strunk III’s metal wreath. 11 a.m.-5 p.m. Saturday. 620 First Ave.
